What caused Stryker's operating expenses spike in Q4 2024?

Stryker's operating expenses did not spike in Q4 2024. In fact, total operating expenses were $2.43 billion for the quarter, representing a 9.2% increase from the year-ago quarter's level. However, this increase was primarily driven by strategic acquisitions and investments in growth initiatives, rather than a spike in operating expenses. The company's focus on product innovation and strategic acquisitions to sustain growth, along with the completion of several significant acquisitions, contributed to the increase in operating expenses. Additionally, the company's international sales, which constitute about 25% of total sales, presented significant growth opportunities and contributed to the expansion of operating expenses.
